ABSTRACT:
A stapling device developed for orthopaedic use is in two cooperable parts including: a locator (10) in the form of a generally tubular member having a pair of opposed parallel grooves (16) extending longitudinally over one end portion of the inner surface of the member to receive the legs of a staple (30) of appropriate size entered head first into the one end, and having pin or other penetrating means (17) projecting from the one end of the member for a short length compared to the grooves to be entered into bone or other material to stabilize the locator in a desired position relative thereto; and a punch (20) longer than the locator and slidable therein over substantially the whole locator length from its other end to drive a staple therefrom. The one end portion of the locator preferably has its interior narrowed to a slot form (14) with the grooves at the slot ends, and its exterior tapered or otherwise similarly shaped with pins at each end adjacent the grooves, to facilitate staple location. Also the locator and punch preferably incorporate stop formations (15, 23; 24) to obviate undue penetration of a driven staple.
